.. or any of the 0w40 oils out there. They are all well-engineered. IndyCars (Castroneves) use Pennzoil Ultra SRT 0w40 straight (Dodge dealers, eBay, Amazon), but Pennzoil's Walmart Euro 0w40 is also similar. M1 0w40 of course great too. A little thicker wich may quiet the valvetrain a bit, but not too thick at all. Very stout formula.
Meets tough euro specs like MB 229.5, Porsche A40, grueling tests they put them through.
